There are several getters for various image data:

getFrameValue -  Gives you the width and height (in pixels) of the image, and a 
                 pointer to the start of the pixel array of a Pds::Camera::FrameV1 object.

getOpal1kValue - an alias for getFrameValue

getTm6740Value - an alias for getFrameValue

getCspadQuad   - Gives you a pointer to the first position in the array of pixel
                 data from the XPP CsPad detector (or alternatively you can get 
                 a pointer to the Pds::CsPad::ElementV1 object itself).

• FrameDetector (general):

  Code Block
  int getFrameConfig (FrameDetector det); int getFrameValue(FrameDetector det, int& frameWidth, int& frameHeight, unsigned short*& image );

  fetches an image from the FrameDetector of your choice.
  Specify the detector (using an appropriate enum), and getFrameValue will direct your pointers to the width and height of the image as well as the start of the pixel array.

  Code Block
  Other frame detectors: AMO: AmoVmi AmoBps1 AmoBps2 SXR: SxrBeamlineOpal1 SxrBeamlineOpal2 SxrEndstationOpal1 SxrEndstationOpal2 SxrFccd XPP: XppSb1PimCvd XppMonPimCvd XppSb3PimCvd XppSb4PimCvd

• XPP CsPad detector:

  Code Block

  namespace Pds { namespace CsPad { class ConfigV1; }} int getCspadConfig (Pds::DetInfo::Detector det, unsigned& quadMask, unsigned& asicMask); int getCspadConfig (Pds::DetInfo::Detector det, Pds::CsPad::ConfigV1& cfg); namespace Pds { namespace CsPad { class ElementV1; }} int getCspadQuad (Pds::DetInfo::Detector det, unsigned quad, const uint16_t*& pixels); int getCspadQuad (Pds::DetInfo::Detector det, unsigned quad, const Pds::CsPad::ElementV1*& data);

  For an example of how to draw an image as a 2D root histogram, see the myana_cspad.cc example.

• Fast CCD camera:

  Code Block

  int getFccdConfig(FrameDetector det, uint16_t& outputMode, bool& ccdEnable, bool& focusMode, uint32_t& exposureTime, float& dacVoltage1, float& dacVoltage2, float& dacVoltage3, float& dacVoltage4, float& dacVoltage5, float& dacVoltage6, float& dacVoltage7, float& dacVoltage8, float& dacVoltage9, float& dacVoltage10, float& dacVoltage11, float& dacVoltage12, float& dacVoltage13, float& dacVoltage14, float& dacVoltage15, float& dacVoltage16, float& dacVoltage17, uint16_t& waveform0, uint16_t& waveform1, uint16_t& waveform2, uint16_t& waveform3, uint16_t& waveform4, uint16_t& waveform5, uint16_t& waveform6, uint16_t& waveform7, uint16_t& waveform8, uint16_t& waveform9, uint16_t& waveform10, uint16_t& waveform11, uint16_t& waveform12, uint16_t& waveform13, uint16_t& waveform14);

  Configures the information from the Fast CCD. Fills arguments with values depending on how the image/waveform data were taken. There is no getFccdValue in main.hh, so I think you need to use getFrameValue for this .

• PnCCD camera (used by CAMP):

  Code Block
  int getPnCcdValue (int deviceId, unsigned char*& image, int& width, int& height );

  This camera has 4 links, each link provides a 512 x 512 x 16 bit image. This function combines the four images to a single 1024 x 1024 x 16 bit image.
  deviceId can be PnCcd0 or PnCcd1, width and height are the number of pixels in each direction.
